Oh YES. That book is so amazing. And worth every penny.
I hope it doesn't come off as superficial when I say that I'm also really grateful for the gorgeous art -- it's not that the story wouldn't be worth telling anyway, of course it would, but I really dig it when comics take the visual part of sequential storytelling seriously and deliver, for a lack of a better word, some eyecandy.
I also loved the decision to make up alphabets and symbols so you cannot read the language, either. Or make simple, everday machines look alien and strange so you'd be just as confused about which buttons to press. This book doesn't make it easy for you, and that's good.
